A snapshot of the climate in the Middle Pleistocene inferred from a stalagmite from central Japan

Autor: Masataka Sakai, Masako Hori, Ryu Uemura, Bassam Ghaleb, Daniele L. Pinti, Mahiro Yumiba, Masafumi Murayama, Akihiro Kano

Publikováno v: Geoscience Letters, Vol 11, Iss 1, Pp 1-7 (2024)

Abstract Stalagmites are useful archives in reconstructing paleoclimates: most paleoclimate studies used stalagmites that are distributed in specific locations and ages. We examined a stalagmite (GYM-1) collected from Nara Prefecture, central Japan,

Paleomagnetic techniques can date speleothems with high concentrations of detrital material

Autor: Elisa M. Sánchez-Moreno, Eric Font, F. Javier Pavón-Carrasco, Luca A. Dimuccio, Claude Hillaire-Marcel, Bassam Ghaleb, Lúcio Cunha

Publikováno v: Scientific Reports, Vol 12, Iss 1, Pp 1-14 (2022)

Abstract The U-series dating of young and ‘dirty’ speleothems is challenging due to difficulties in assessing the isotopic composition of detrital contaminants and the low-abundance of 230Th generated in situ. Here we propose a new dating approac

The potential of gypsum speleothems for paleoclimatology: application to the Iberian Roman Humid Period

Autor: Fernando Gázquez, Thomas K. Bauska, Laia Comas-Bru, Bassam Ghaleb, José-María Calaforra, David A. Hodell

Publikováno v: Scientific Reports, Vol 10, Iss 1, Pp 1-13 (2020)

Abstract Carbonate cave deposits (speleothems) have been used widely for paleoclimate reconstructions; however, few studies have examined the utility of other speleothem-forming minerals for this purpose. Here we demonstrate for the first time that s

Gypsum Precipitating From Volcanic Effluent as an Archive of Volcanic Activity

Autor: Vincent J. van Hinsberg, Kim Berlo, Daniele L. Pinti, Bassam Ghaleb

Publikováno v: Frontiers in Earth Science, Vol 9 (2021)

Records of volcanic activity are a key resource in volcano monitoring and hazard mitigation. The time period for which such records are available and the level of detail vary widely among volcanic centers and there is, therefore, a need for supplemen

PALÉORIVAGES, DUNES CÔTIÈRES ET OCCUPATIONS HUMAINES À L’EMBOUCHURE DE L’OUED TAMRI, MAROC ATLANTIQUE, AU PLÉISTOCÈNE SUPÉRIEUR (SIM 5)

Autor: Abderrahmane OUAMMOU, André WEISROCK, Sanda BALESCU, Abdelhadi EL OUAHIDI, Bassam GHALEB, Gilles GUERIN, François HARDY, José MANGAS-VIÑUELA, Salah ABDESSADOK, Abdessamad CHARIF, Louis ROUSSEAU, Michel LAMOTHE, Christophe FALGUERES

Publikováno v: Journal of Water and Environmental Sciences, Vol 3, Iss SI (RQM9), Pp 391-406 (2019)

At the left side of the OuedTamri mouth, a palaeo-sea-level (Unit 1) consists of marine and fluvio-marine deposits at ca. + 6 m a.s.l. The U/Th dating method applied to one marine shell of Patella sp. has yielded ages of 100,02 ± 1,662 ka and 101,18

Reconstruction of Atmospheric Lead Pollution During the Roman Period Recorded in Belgian Ombrotrophic Peatlands Cores

Autor: Mohammed Allan, Daniele L. Pinti, Bassam Ghaleb, Sophie Verheyden, Nadine Mattielli, Nathalie Fagel

Publikováno v: Atmosphere, Vol 9, Iss 7, p 253 (2018)

Two peat cores from two bogs were used to record changes in the atmospheric Pb accumulation rate (Pb AR) in Belgium during the Roman period. The two records were compared to assess the reliability of peat cores as archives of atmospheric Pb depositio

Using Lead Concentrations and Stable Lead Isotope Ratios to Identify Contamination Events in Alluvial Soils

Autor: Diane Saint-Laurent, Julien St-Laurent, Marlies Hähni, Bassam Ghaleb, Camille Chapados

Publikováno v: Applied and Environmental Soil Science, Vol 2010 (2010)

Soils contaminated with hydrocarbons (C10–C50), polycyclic aromatic hydrocarbons (PAHs), and other contaminants (e.g., As, Cd, Cu, Pb) were recently discovered on the banks of the Saint-François and Massawippi rivers. Alluvial soils are contaminat
